Types

type WrappedEntity

type WrappedEntity struct {
	flow.Entity
	// contains filtered or unexported fields
}

WrappedEntity is a wrapper around a flow.Entity that allows overriding the ID. The has 2 main use cases:

• when the ID is expensive to compute, we can pre-compute it and use it for the cache
• when caching an entity using a different ID than what's returned by ID(). For example, if there is a 1:1 mapping between a block and an entity, we can use the block ID as the cache key.

func NewWrappedEntity

func NewWrappedEntity(id flow.Identifier, entity flow.Entity) *WrappedEntity

NewWrappedEntity creates a new WrappedEntity

func (WrappedEntity) Checksum

func (w WrappedEntity) Checksum() flow.Identifier

Checksum returns th cached ID of the wrapped entity

func (WrappedEntity) ID

func (w WrappedEntity) ID() flow.Identifier

ID returns the cached ID of the wrapped entity
